Suppose that both planets are spherical. radius of Saturn =142984/2=71,492
Area of Jupiter = 4πr² ==>4π(71,492)² =6.4228 x 10^10
Area of Saturn ==>(6.4228 x 10^10)x(0.599) ==>3,84726 x 10^10
Radius of Saturn = 4πr² =3,84726 x 10^10==> r²=3,0219 x 10^10
and r √(,0219 x 10^10) = 174.000 km & D = 384,000 km
At the end of Round 3, David's score would be 2000.
(f+g)(x) = 8x+2
(f-g)(x) = 4x-6
Step-by-step explanation:
Given

we have to find
<u>a. (f+g)(x)</u>

<u>b. (f-g)(x)</u>

Hence,
(f+g)(x) = 8x+2
(f-g)(x) = 4x-6

Answer:
2√2.
Step-by-step explanation:
We use the Pythagoras Theorem:
x^2 = 2^2 + 2^2
x^2 = 8
x = √8
= 2√2.
